Abstract
This study was prospective interventional study to extend the patency rate of hemodialysis access and maintain its use.
We had 27 patients known to have end stage renal disease on hemodialysis were included in the study, they presented to the vascular surgery unit, in Suez Canal University hospital, (96%) of the patients presented with thrombosed AVF and (4%) of the patients presented with thrombosed AVG. (41%) patients were diabetic. (48%) patients were hypertensive. (22%) patients have Ischemic Heart Disease. (15%) patients have SLE. (11%) patients have chronic liver disease with HCV +ve results.
The study showed overall success rate (70%) evidenced by post-operative palpable thrill and usage in HD, (7%) of them got rethrombosed after 3 months of follow up, (63%) patients kept patent functioning AVF for more than 6 months. Among the (63%) of patients who kept patent functioning AVF for more than 6 months (18.5%) of patients were having primary occluded AVF and among the (7%) of patients who got rethrombosed after 3 months of follow up there was (3.5%) of patients was having a primary occluded AVF and among the (30%) of patients who failed to regain functioning AVF after the procedure (7%) of patients were having primary occluded AVF. Primary occluded AVFs success results were generally higher than secondary occluded AVFs.
In selected cases the combination between thrombectomy and another intervention such as revision of anastomosis in first day occluded AVFs, jump graft insertion over a short segment that wasn`t completely patent and flow limiting after thrombectomy to bypass it, and proximal reinsertion of the vein to the artery in tight anastmotic stenosis was associated with higher success rate.
